An exterior repaint in Lake County has to survive freeze-thaw cycles, lake-driven humidity and a hundred-degree summer swing. That makes prep and timing the whole job. Coating over a surface that is damp, chalky or still holding failing paint is why a repaint fails in three years instead of ten. We wash, let it dry, scrape back what is failing, prime the bare spots and caulk the joints before the first finish coat. And we book the work inside the season rather than squeezing it into November because the calendar got tight.

The Lake County painting year
Interior work runs every month. Exterior is weather dependent, so the spring slots go first.
Prep
An exterior repaint fails from the substrate up, not from the paint down. Almost every peeling job we are called to redo failed because of what happened before the paint went on.
Washing. Every surface gets cleaned before anything else. Lake County exteriors carry mildew on north-facing walls, chalking on older painted surfaces, and pollen and dirt everywhere. Paint over any of that and the bond is compromised from day one.
Scraping and sanding. Loose and failing paint has to come off, and the edges of what remains have to be feathered so the transition does not telegraph through the new coat. This is the slowest part of any exterior job.
Rot and repair. Soft trim, failed sills, damaged fascia and rotted corner boards get repaired or replaced before painting. Paint over rot and you have hidden the problem for one season.
Caulking. Joints, seams, around windows and doors, and where trim meets siding. Old failed caulk gets cut out rather than caulked over.
Priming. Bare wood, repairs and any tannin-prone species need primer. Skipping it is why knots bleed through a year later.
Lead paint. Houses built before 1978 can have it. Testing and lead-safe practices are a legal requirement on those, not optional, and it changes the scope. If your house is older, say so up front.
Weather
Exterior paint has real temperature and moisture limits, and pushing them is how a job fails in year two.
The window is roughly late April through October. Most exterior coatings want surface and air temperatures above about 50°F, and some want more. Just as important, the temperature has to stay above that overnight while the film is still forming.
Late spring is wetter than people expect here. Siding has to be dry before it is coated, and a wall that got rained on yesterday is often still holding moisture today. We check rather than assume.
High summer has the opposite problem. A south or west wall in direct August sun can be well over 100°F, and paint applied to a hot surface flashes off before it can level and bond. We follow the shade around the house through the day rather than working the same wall from morning to evening.
Dew point matters in autumn. September and October afternoons are ideal, but the window closes earlier in the day. Paint applied at four in the afternoon on an October day can be wet when the dew falls.
Lakefront exposure. Houses in Highland Park, Lake Forest, Lake Bluff and along the shore take more wind and moisture off the lake than an inland house in Mundelein does. That affects both scheduling and which product goes on.
If we tell you a week is not paintable, that is why. Painting through it costs you the job.
Around the county
Exterior scheduling in Lake County is decided by exposure as much as by the calendar. Houses along the lake through Highland Park, Highwood, Lake Forest and Lake Bluff take wind-driven moisture off the water, which means north and east elevations carry mildew every year and dry more slowly after rain than an inland wall does. Inland through Libertyville, Mundelein, Grayslake and Vernon Hills, the constraint is more straightforward heat and sun, and the work follows the shade around the house through the day. Older housing stock in Waukegan, North Chicago, Zion and Highwood raises the lead question — anything built before 1978 needs testing and lead-safe practices, and that is a legal requirement rather than a preference. Newer subdivisions through Gurnee, Round Lake and Lindenhurst are mostly vinyl and fiber cement with painted trim and doors, which is a smaller scope than a full wood-sided repaint. Whatever the house, the same two rules decide whether the job lasts: the surface has to be genuinely dry, and it cannot be baking in direct sun when the coating goes on.
How it works
We look at the surfaces, not just the rooms. Prep is what the number is built from, so it is what gets measured.
You get the surfaces, the products, the number of coats and the price in writing before anything is booked.
Interior any month. Exterior inside the season, not squeezed into the end of it.
We walk the finished work with you under real light and fix anything on the list before the final invoice.

Questions
By surface area and by the amount of preparation the surfaces need, which is the part that varies most between two houses that look similar. A wall that needs washing, filling, sanding and priming is several times the work of one that needs a coat. You get the scope in writing — surfaces, products, number of coats — so you can compare quotes on the same basis rather than on a single number.
Interior work runs all year, and January through March is the easiest time of year to book. Exterior work is weather dependent and needs surface temperature and dryness within range, so it runs roughly April through October in Lake County. We would rather tell you to wait for spring than put a coat on in November that fails by summer.
A single room is usually a day or two. A whole-house interior runs one to two weeks depending on how much trim and how much prep. A full exterior is typically one to two weeks, and the weather decides more than the crew does. You get a schedule up front, and you are told when it moves.
No. Interior work is done room by room so the house stays livable, and each room is put back at the end of each day rather than at the end of the job. If a kitchen is being refinished you will lose the use of the cabinets for a few days, and we plan that with you rather than around you.
Roughly April through October, and it varies with the spring. What matters is surface temperature and dryness rather than the date. Booking in winter for a spring slot gets you the dry early window, which is the best of the year for adhesion and curing.
